The following two very cool products/projects are from Make Magazine. A very highly recommended magazine for the DIY’ers.
Can’t find an open source MP3 player? Neither could we. Here’s an idea: Build your own. Daisy is an easy-to-build, pocket-sized open source MP3 player.
Producing sound as good as an iPod, the Daisy can access 65,000 tracks, play 48khz WAV files as well as MP3’s, and unlike an iPod, has batteries that you can actually change. But the big thing about Daisy is the ease with which it interfaces with
so many devices, including the Make Controller.
It is the perfect MP3 kit for Makers, for it is easily integrated into kiosks, displays, art installations, or just about anything else you can dream up.
Make your own iPod battery-pack and recharger! Build your own MintyBoost: a small & simple (but very powerful and very MAKE-like)USB charger for your iPod (or
other mp3 player), camera, cell phone, and any other gadget you can plug into a USB port to charge.
The charger circuitry and 2 AA batteries fit into an Altoids gum tin, and will run your iPod for hours, 2.5x more than you’d get
from a 9V USB charger! You can use rechargable batteries too. Some soldering is necessary, but even if you’ve never soldered before it should be pretty easy.
Tested with iPod nano/mini/photo/video/shuffle, Blackberry, iPaq, LuxPro Tangent, Rio Carbon, Samsung T809 and more. Batteries and tin not included. If you live in an area that doesn’t have Altoids gum, you can buy a tin (including the gum)
